UNITED STATES PATENT OEEIGE,

WILLIAM C. HARLOW, OF MEDFORD, MASSACHUSETTS.

i IMPROVEMEN'Is IN ANIMAL-.SHEARING MACHINES.

Specification forming part of Letters Patent No. l 59,547, dated February 9, 1875; application filed December 7, 1874.

To all whom it may concern:

Be it known that I, WILLIAM C. HARLOW, of Medford,in the county of Middlesex and State of Massachusetts, have invented certain newV and useful Improvements in Machines for Shearing Animals, of which the following is a specication: p

The object of my invention consists in the simple and effective arrangement of a diaphragm-pump, with certain operating parts, upon a stand, whereby the motive power may be transmitted'through flexible tubes, for the purpose of operating at a distance from said device animal-shears. Said animal-shears, being already patented, are introduced into this specication anddrawings for the purpose of more fully elucidating the present invention and the mutual operation of and connection between the two inventions.

Figure 1 is an elevation of the generator. Fig. 2 is a vertical section of the same. Fig. 3 is a plan of the generating-chamber. Figs. 4 and 5 are views of the clipper. Fig. 6 is a longitudinal section of the same.

As the clipper shown in Figs. 4, 5, and 6 is fully described in Letters Patent issued to L. B. Hamilton and Charles F. Harlow, entitled improvements in machines for shearing animals, dated September 1, 1874, and numbered 154,603, it need not be herein described.

A, Figs. 1 and 2, represent a standard for holding the generating part of my device. B is the generating-chamber, which is divided by the diaphragm L, Fig. 2, into two cham bers, C and C'. 'This diaphragm is made to oscillate back and forth by the crank-shaft N1, operating through the pitman N and piston M. (See Fig. 2.) N2 is a driving-wheel. P, Fig. 1, is a grinding or polishing` wheel attached to the standard A, and is driven by the belt P'. The chambers G and C' of the generator are connected with the workingchambers S S' of the clipper by the flexible tubes E and E', so that any pressure in the chamber Gis transmitted to the chamber S. The same may be said of the chambers C' and S'. When the diaphragm L of the generator is operated, as it may be by turning the wheel N2, the air in the chambers G and C' is alternately expanded and compressed, and this eX- pansion and compression takes place in the working-chambersS and S' of the clipper, which action gives motion to the lever I, and through it to the cutter I', Fig. 6. H and H', Figs. '1 and 4, represent a short metallic coil, which is to be slipped onto the ends of the iexible tube E and E'. As the Ilexible coils extend over with the flexible tubes onto the rigid pipes D and D', it may be seen that these coils Will serve as supports for the flexible tubes,`

and prevent them from being abruptly bent, and thus interfering with the free iiow of the air.

I claim as my invention- In an animal-shearing machine, the combination of the standard A, having' at its upper end the chamber C C', outlets D D', diaphragm L, and rod M, all constructed and arranged substantially as described.

WILLIAM C. HARLOW.
